Partial knee replacement, also known as unicompartmental knee arthroplasty, is a surgical procedure aimed at replacing only the damaged compartment of the knee joint with artificial implants. This procedure becomes necessary when conditions such as osteoarthritis are localized to one part of the knee, causing significant pain and impairment in knee function. During surgery, the damaged portion of the knee joint, typically the medial or lateral compartment, is removed and replaced with metal and plastic components to restore function and alleviate pain.

Before undergoing partial knee replacement surgery, it's crucial to understand several key aspects. Firstly, discuss thoroughly with your healthcare provider about the need for partial knee replacement, considering factors such as persistent knee pain, swelling, or limited range of motion. Understand the risks and potential complications associated with the procedure, including infection, blood clots, or implant loosening. Recognize the importance of post-operative rehabilitation in achieving optimal outcomes, including physical therapy and activity modification. Prepare your home environment for recovery, ensuring accessibility and safety measures are in place.
Several conditions must be met before considering partial knee replacement surgery. Patients should have exhausted non-surgical treatments such as medication, physical therapy, or corticosteroid injections. They should be in good overall health, with any underlying medical conditions well-managed to minimize surgical risks. Surgeons evaluate factors such as the extent of cartilage damage, alignment of the knee, and the integrity of the ligaments when determining candidacy for partial knee replacement surgery. Additionally, patients must be committed to post-operative rehabilitation for successful recovery.
Partial knee replacement surgery involves removing the damaged portion of the knee joint and replacing it with artificial implants. This procedure aims to relieve pain, improve knee function, and restore range of motion. During surgery, the surgeon carefully removes the damaged cartilage and bone from the affected compartment, prepares the bone surfaces, and implants the artificial components, including a metal femoral component and a plastic tibial spacer. Post-operative rehabilitation plays a crucial role in recovery, focusing on strengthening exercises, knee mobility, and activities of daily living.
After partial knee replacement, diligent postoperative care is essential for optimal recovery. This includes proper wound care to prevent infection and managing pain with prescribed medications. Adherence to physical therapy protocols is vital for restoring knee joint function and mobility. Patients should gradually progress from using assistive devices to independent knee movement, following guidelines provided by their healthcare team. Regular follow-up appointments with the surgeon are necessary to monitor progress and address any concerns. Patients should also maintain a healthy lifestyle, including proper nutrition and exercise, to support long-term knee joint health and overall well-being.
By addressing the damaged portion of the knee joint, partial knee replacement surgery aims to improve function and alleviate pain, enabling patients to regain an active lifestyle. However, understanding the procedure, its risks, and the importance of post-operative rehabilitation is crucial for successful outcomes.
